Potential vegetable oils of Indian origin as biodiesel feedstock — An experimental study

This study presents various vegetable oils from edible and non-edible sources for preparation of biodiesel using KOH as catalyst and methanol as alcohol. Maximum biodiesel yield from all vegetable oils was obtained under following optimum conditions: reaction temp., 70°C; reaction time, 1 h; catalyst amount, 1% (by oil wt); and methanol to oil molar ratio, 6:1. Characteristics of biodiesel at optimum conditions were as per ASTM standards.
